Re: Problems with LRA for KNF/KNC in GCC 4.9

Hi Vladimir,

I'm trying to apply KNF and KNC changes for GCC 4.9 (they have been
applied for 4.7 before), but I have some problems with LRA.
I've tried to build cross compiler for KNC. During the compiling of
libgcc/libgcc2.c the compiler becomes locked inside the loop in
function lra () and can't quit it. There is no error messages, just
infinite looping.
Could you please advise me, what I need to fix?
Patch and reload dump (first few iterations) are in attach.


Andrey, I've just wanted to start to work on your problem. Unfortunately, I can not apply your patch as it conflicts with avx512 work recently added.

So could you send me an updated patch and the preprocessed file on which LRA cycles.

Please use gcc-patches mailing list as it more fit for your problem.

Thanks.
